How do we politely say that Mexico and Central America have a large population of dysfunctional, anti-social, criminally minded sociopaths. And we don't want them here, either. Sure, the good Mex and CA citizens reject them (unless they're close kin, then all bets are off) and they've ruined their lives by being convicts, but we don't want them either. But no doubt the "good citizens" just figure "Hey if they go to the US then WE'RE rid of them!"
